RAIL-BASE.

Specification of Letters Patent.

Patented July 2, 1912.

Application filed March 4, 1912. Serial No. 681,322.

To all whom it may con-cam:

Be it known that I, ADRIAN D. DAVIES, a citizen of the United States, residing at Chase, in the county of Rice and State of Kansas, have invented a new and useful Rail-Base, of which the following is a specification.

This invention relates to railways, and has for its object to provide elongated base plates which are adapted to set end to end at each side of the track and longitudinally thereof and over which the rails may pass, the said plates serving to support the rails in the manner of ordinary wooden ties.

Another object of the present invention is to provide means for engaging the base flanges of the rails to the plates; means for catching derailed wheels at each side of each of the rails; and means for preventing the base plates from shifting laterally or side wise to retain the rails in proper track gage.

A further object of the present invention is to provide a base plate of this character which is comparatively simple in construction and inexpensive to manufacture, and which in use will be convenient and eflicient.

With the foregoing and other objects in view, this invention resides inthe novel construction of base plate as elicited in the following description, it being understood that this device is susceptible of slight altera tions or deviations in its details within the scope of the appended claims without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings in its preferred embodiment, wherein similar reference charaeters denote corresponding parts, and wherein- Figure l is a fragmental perspective of a base plate constructed in accordance with the present invention as in use. Fig. 2 is a plan view thereof. Fig. 3 is a transverse sectional view. Fig. l is a fragmental transverse sectional view of a detail and on an enlarged scale.

Referring specifically to the drawings, the base plate is designated by the numeral 5, this plate being elongated in form and being constructed of suitable metal which will withstand the stresses and strains to which it may be subjected. This plate 5 along its median line is provided with a depending longitudinal rib or flange 6, which tapers toward the lower edge, the bottom of the plate 5 at the sides of the rib or flange 6 being inclined to the edges thereof, as designated by the numerals 7. A pair of spaced upstanding longitudinal ribs 9 extend lengthwise of the plate 5 and are adapted to snugly receive the base flange of a rail, the said ribs 9 being of a height approximately one-half the height of the rail and having means at points along "the lengths thereof for engaging the base flange of the rail. The means for engaging the base flange of the rail comprises a tongue 11 formed in the rib 9 by means of slits or cuts 10, which tongue 11 may be bent inwardly and downwardly to engage the base flange of the rail. In this manner, the rail. may be held upon the plate and may shift longitudinally thereon to compensate for the expansion or contraction of the rail. At the sides of the pair of ribs 9 are a plurality of upstanding longitudinal ribs 8, which are spaced at suitable distances from the ribs 9 to the edges of the plate 5, there being in this case three of the ribs 8 at each side of the plate. The ribs 6, S and 9 are preferably constructed integral with the plate 5, the plate 5 being preferably rolled in the formation thereof, as will be understood by those skilled in the art. The ribs 8 are approximately of the same height as the ribs 9, and the ribs 9 and 8 at the respective sides of the median line of the plate 5 are preferably equi-distant from the median line, whereby the plate is symmetrical on the respective sides of the median line.

In practice, the base plates 5 are laid 011 the road-bed ,at the opposite sides of the track and are brought end to end, in which event the ribs 6, 8 and 9 are continuous throughout the length of the track. The rails, designated by the letter R in the drawings, are then laid upon the base plate 5, the base flanges thereof being received by the ribs 9 which prevent the rails from shifting laterally upon the said plate. The tongues 11 along the ribs 9 at various points thereof are then bent inwardly and downwardly to engage the base flanges of the rails to retain the rails upon the plate. The plate 5 in being applied to the road-bed causes the rib 6 to be embedded into the road-bed, and the inclined side 7 of the bottom of the plate to seat upon the roadbed to support the plate, and the plate thereby having sufficient bearing upon the roadbed to be supported against undue depression into the road bed but to permit the plate to yield slightly as is essential in rail 7 plate 5 and are connected by the usual fish plate F. It is preferable to provide a plurality of tongues 11 at the joints of the rail to eifectively retain the ends of the rails on the plate, and to also prevent the ends of the rails from disengaging entirely from the tongues due to the expansion and contraction of the rails. In the manner described, the rails of the track are supported in a convenient and effective manner, and the base plates are simple in construction and are capable of manufacture at a comparatively low cost, and when once installed, the plates may support the rails for an indefinite period, and need not be replaced from time to time as is-the case with wooden ties. Should a wheel, or wheels, of a locomotive passing over the track become de railed, the same will be caught by the ribs 8, which ribs will then serve as an auxiliary track until the locomotive may be brought to a stop, in which event, the derailed wheel or wheels may be again positioned upon the rail or rails. In this manner, accidents and wrecks may be avoided.

Having described the invention, what is claimed as new is 1. A base plate for rails embodying spaced longitudinal ribs at the sides of the median line for snugly receiving the base flange of a rail, and each having slits therein at points along the lengths thereof, forming tongues designed to be bent into engagement with the base flange of the rail, means at each side for catching derailed wheels, and means Copies of this patent may be obtained for five cents each, by addressing the Washington, .D. G.

snugly receive the base flange of a rail and each having slits therein at points along the lengths thereof forming tongues adapted to be bent into engagement with the base flange of the rail, and a plurality of upstanding longitudinal ribs at each side of the aforesaid ribs for catching derailed wheels.

4-. A base plate for rails comprising an elongated plate having a pair of longitudinal upstanding ribs to snugly receive the base'flange of a rail and each having slits therein at points along the length thereof forming tongues adapted to be bent into engagement with the base flange of the rail, a plurality of upstanding longitudinal ribs at the sides of the aforesaid ribs for catching derailed wheels, and a depending longitudinal rib at the median line adapted to be embedded in the road-bed, the respective aforesaid ribs being disposed at thesides of the median line. v

In testimony that I claim the foregoing as my own, I have hereto aflixed my signa-' ture in the presence of two Witnesses.
